- the invention also relates to a Pt / Preparation method and application of graphene catalyst.
- Proton exchange membrane fuel cell It is a new generation of hydrogen-fired power generation device.

The outstanding advantages of start-up and long life have become the most promising fuel cell.
- PEMFC electrocatalyst is one of the key factors restricting its commercialization. Therefore, the research on electrocatalyst becomes PEMFC.

- graphene exhibits a strong quantum effect and good electron conductivity. It is found by the first principle that the platinum group can be stably supported on the graphene, and the adsorption of carbon monoxide or hydrogen on the platinum particles is reduced by the presence of graphene, which is more favorable for the reaction in the fuel cell. Therefore, graphene can be used as a good carbon carrier.
